 ===== Principle =====
-**FOGHAT** is a humidity and temperature profiler [[instruments:hatpro:hatpro|(HATPRO)]] manufactured by RPG. It measures 7 brightness temperatures in the water vapor line (22.24 GHz) and 7 in the oxygen complex (60 GHz), the former brightness temperatures are used for water vapor profiling, the latter for temperature profiling. Measurements around the water vapor line are used to derive integrated water vapor (IWV) and integrated liquid water (LWP) content. \\ As of March 2018, FOGHAT was deployed at the Iquique site in the framework of the {{http://sfb1211.uni-koeln.de|CRC 1211 Dry Limit}} and performed synchronous measurements with the [[instruments:joyrad94:joyrad94|Cloud Radar JOYRAD-94]] and a HALO Photonics windlidar. Synergetic measurements of FOGHAT, the cloud radar JOYRAD-94, and the windlidar deployed at the [[sites:iquique|Iquique]] site are used to study fog and clouds forming at the coast of North Chile at the edge of the Atacama.
+**FOGHAT** is a humidity and temperature profiler [[instruments:hatpro:hatpro|(HATPRO)]] manufactured by RPG. It measures 7 brightness temperatures in the water vapor line (22.24 GHz, K-band in the IEEE nomenclatur) and 7 in the oxygen complex (60 GHz, W-band), the former brightness temperatures are used for water vapor profiling, the latter for temperature profiling. Measurements around the water vapor line are used to derive integrated water vapor (IWV) and integrated liquid water (LWP) content. \\ As of Oktober 2019, FOGHAT is deployed in a site south-west of France within the framework of the [[https://www.umr-cnrm.fr/spip.php?article1086&lang=en | SoFog3D campaign]] and performs synchronous measurements with a mobile profiler which consists of a Vaisala CT25K ceilometer, a Vaisala WXT weather station, a METEK micro rain radar, an Ott Parsivel optical distrometer and an hemispheric camera. Together, the measurements are used to study physical fog processes and the evolution of fog events.
